Samos Stamp Sc#n78A?

I have obtained this stamp from Samos, Greece, 1912. My question is, since it is imperforate, should I classify it as SC#N78A?

With such large margins I would first assume it was a cutout from stationery.

Can we see a view of the back to exclude the possibility of a stationery cutout? It certainly looks like a possibility.

Not a stationary , color is the same as the regular stamp . Color range is large on this stamp . Edges are fine ,stamp is stained .Should be a fine white paper .

correction the imperf stamps {two yellow stamps } are not on fine white paper but a darker tan color also seems to be thinner paper .

You can get margins like that, so it seems genuine enough.

Thanks everyone!! Without setting a precedent, I greatly appreciate your knowledge and valuable contributions, Rogdcam. Even when we clash... you're valuable to me and community. I wish you had a better read and understanding of my intentions when I post.
Maybe a stupid question, but the series in the image are CTO, right?

What family doesn't have quarrels?

CTO for certain.

The same postmark, but different date, applied in Vathy on a cover sent registered to the stamp dealer Richard Borek, Braunschweig, Germany.

Arrival postmark applied in Braunschweig, Germany.

C.T.O. ---Cancel to order can mean a lot of different things . Those above could be canceled at the counter and handed back {like in the Saar } . Can also mean remaining inventory after the post office went to a new issue. Then the most often method ,canceled at the time of printing {like in the Iron curtain and African new issues} So these could be hand backs for a dealer is my guess .
